Why Orientation Lock?

When using an Android tablet, you might find that some applications do not support landscape mode or specific orientations. This was quite troublesome for me. I tried several screen orientation locking apps available on the market, but they were overloaded with features. I simply needed an app to lock the screen orientation, so I decided to create one myself.

The principle behind locking the screen orientation is very simple: it involves using a floating window to render a view in a specified orientation. This is just a straightforward application, and I wanted to keep it lightweight. Therefore, I implemented it using native methods without any third-party libraries. Pretty cool, isn’t it?
